So I have been researching some motors online and figuring what I want to do with my cherokee. I hear that the EFI is Fuel Density, which sucks A$$. The 4.0 run extremely lean? So if I were to stroke the motor what would I do to get the fuel curve right. Aside from that, I have borla catback with no cat, and a 62mm throttle body with a 62mm throttle body helix bore spacer, would the jet performance stage 2 setup help fix my fuel curve? I am planning on adding a header shortly, any help on which ones are good? I want a Borla one, but am subject to change. Thanx. BTW its a 94 jeep cherokee 4.0 H.o.
